1 TofaZZ whomii may concern: I I

Be it known that I, FRANK A. ADAMS, a citizen of the United States of America, and residing at Bochester,in the county of Monroe and Stateof New York, have invented certain new and useful Improvements Coupling Devices, of which the following is a speclfication. 1 p p My invention relates to a coupling device, andis more particularly intended to be, used as aquickly detachable connection between two pipes, or between aflexible tube anda pipe as for instance where it is desired to connect a rubber tube on the end of a faucet. y

A principal object o-f the invention is to provide a simple and practical mechanism which can be economically manufactured, and e ificiently accomplishes the intended purposes.

, A further object of the improvement is to provide a construction that insures gripping the end of a pipe tightly, and'which also elfects a close, watertight connection between the faucet and the tube that is connected thereto.

An additional purpose of the invention is to provide a construction that lends itself readily to quick and easy attachment, and

which alsoaccommodates itself without difficulty to various types of. faucets, including those in which the end surface of the, faucet is disposed at other than a right-angle to the longitudinal axis thereof, the seat of the coupling device adjusting itself automatically'to such end ofa faucet.

Other objects and advantages of theimprovement will appear from the following detailed description, in conjunction with the accompanying drawing, the novel; features out in the claims following the I being pointed description. y

In the drawing; v -Figure 1 is a side elevation showing a preferred embodiment of the invention as applied in actual use to a faucet; I g

Figure 2 is an enlarged vertical sectional view ofthe same;

illustrated in Figure 1 Figure-4c is a horizontal'sectional view on .line 47- 1 of Figure-1';

modification of seat construe Referring more particularly to the draw- I 'ing,-whicl1 illustrates one of thevariou's possible practical adaptations of the inventlon,

A designates the end of a pipe or faucet with which the connection is to be made.

The 1nv,ent1on,in the'structure shown, 111- cludes a rod like memben'specifically a tubularmetal support in the form of a pipe B, having thecorrugated end a to receive a, rubber tube or similar flexible connection. The

tubular support B is provided with a seat' for engagingthe'faucet A, and in the form lllustrated in Figure 2, said seat consists of a washer b of rubber vor similar material mounted in a cup 0, which latter isthreaded on the end of the tubular support B'. r

Arranged beneath the cup c, and loosely secured on the tubular support B, is a'vcarrier, preferably in "the formof-a plate ,C,

which carries the gripping devices that engage the faucet and retain the coupling in place. The plate C includes'iipstanding wall d which extend outwardly, forming ears e, between which thegripping devices are pivoted. The gripping devices "consist, of le 'er, arms terminating atone end in V-shaped jaws. 7, adapted to engagea faucetnozzle, as it shown in Figure 4:, and, having at their other ends tail portions 9, by which the gripping.

devioesare operated or released. Toaccomplish. this\end,..the tail portions 9 are cut away to afl ord openings k, for a purpose that will now appear. 1 j

A. preferred form of actuating means is the .mechanical. advantage. devlce shown,

which comprises a sleeve E threaded'for longitudinal) adj u'stment on the support B, and

having fixedly securedlthereon an operating member with finger-pieces fllyby. which the sleeveE rotated to adjust it longitudinally on the support B. The sleeve E has swiveled thereon a collar F including cam members or arms 7r, which enter ,the openings hand en gage the'tail portions 9. Posit oned'aga nst other similar resilient material, while we Zisa ,the carrier plate C is a washer Z of rubber or 4111b hre d d at .S PPQWB were universal yielding motion. The rubb jaws f inwardly. This operation continues until the jaws are in tight engagement with the faucet, and the tail portions can then move no further. Further turning of the sleeve E then causes the tubular support B,

and its seat 0, to move slightly upwardly,

thus forcing the seat into tight engagement with the end of the faucet. The parts are released by turning the finger portions. 7. and

' the sleeve E in the opposite direction to that already described.

While in some cases it practicable to mount the cup 0 fixedly at the end 0 f the tu bular supportB, it is preferable to provide a slight universal relative motion between these parts in order to accommodate a :laucet or pipe where the end is disposed at other than a right angle to the longitudina axis of the faucet, happens inmany basin fittings, where the faucet isinolined to the vertical, although its end is in a horizontal plane. This result is attained by the modilied arrangeinei'its shown in Figures and (3. In Figure 5, the tubular support 18 has its upper end a spun over to afford a lip overlying the adjacent surface 0 of the cup, which is bent downwardly to afford a collar 9) that enters the rubber washer Z, and lies in spaced relation to the tubular support it. With this-construction, the cup which carries the seat 6 is heldon. the tubular support ll. but can yield with reference thereto in various directions. In this form of the device. the carrier plate (l is arranged between the cup and the washer as in the previously de scribed construction.

Still another method of accomplishing this is illustrated in. Figure 6, where the rubber seat Z) is mounted in a cup having a downwardly and inwardly curved flange 1 which engages a? curved surface r formed on the tubular support B. The latter has a lateral flange 5 formed at its upper end, whi n. overlies the flange 9 and prevents sepals the parts, although permitting 1 V, 1 seat 7) is recessed at its bottom to accommodate the flange 8.

The invention may he modified in other respects in. addition to what I have described, without departing from the fundamentalcharacteristics, and this application is intended to cover any'dep artures from" the pecific-disclosure set forth, that'may come within the intended purpose of the improvement and the scope of the following claims.

I claim:

l. The combination with a tubular support providedwith a seat for engaging the end of a pipe, of a carrier mounted on the tubular support and having movement relatively thereto, gripping devices movably arranged on the carrier, and actuating means adjustable on the support and cooperating with said gripping devices.

2. The combination with a tubular sup port provided with a seat for engaging the end of a pipe, of acarrier mounted on the tubular support and having movement relatively thereto, gripping devices pivoted on the carrier, and actuating means having threaded engagement with the support and operatively connected with said gripping devices. I V

3. The combination with a tubular support, of a seat mounted at the end of the support and having a slight universal. movement relatively thereto, of a carrier mounted on the tubular support and having movement relatively thereto, gripping devices movably arranged on the carrier, and actuating means adjustable on the support and cooperating with said gripping. devices.

4. The combination with a tubular support provided with a seat forengaging the end of a pipe, of a carrier mounted on the tubular support and having longitudinal movement relatively thereto ripping jaws 'pivotally mounted on the carrier and 1neluding operating portions, and actuating means adjustable on the support azndengaging with said operating portions.
